Shale Gas is a potential non-conventional energy source to be developed. However, currently shale gas has not been developed optimally in Indonesia. Therefore, the authors aim to help develop the potential of shale gas by indicating the potential for distribution in Indonesia. The research study was conducted by reviewing literature sourced from literature such as journals, articles and books. Based on the research conducted, potential shale gas reserves are found in the North Sumatra Basin, Central Sumatra Basin and South Sumatra Basin. Geochemical method which includes parameters of Total Organic Carbon (TOC), type of kerogen and maturity level (Ro) used to develop shale gas potential in an area. Shale gas can be a substitute for conventional fossil fuels, so further studies are needed so that it can be produced commercially

Fuel is any material that can be converted into energy. For example in daily life humans often use energy sources as fuel for cooking including Gas/LPG, Electricity, Kerosene, Charcoal/Briquettes, Wood and others. The purpose of this study is to classify the distribution of the percentage of fuel used in each district/city in Northern Sumatra. This study discusses the analysis of the K-Means method in the case of the distribution of household percentages by district/city and cooking fuel in North Sumatra through the North Sumatra Central Statistics Agency website. The data is processed into 2 clusters namely high level (C1) and low-level clusters (C2). Thus obtained from 34 districts/cities in North Sumatra 23 regions are grouped in high-level clusters (C1) and 10 regions are grouped in low-level clusters (C2).This needs to be done so that it becomes input in the form of information to the government to find out villages that still have low understanding and have not been fulfilled in a district/city in the Province of North Sumatra.

Sweet Spots

A detailed combined geological and geophysical study in North Sumatra basin has shown that prospective formations for shale play containing gas sweet spots are found to be in shales from Bampo, Belumai, and Baong Formations. Bampo Formation exhibits low shale gas potential with very low to medium in organic material contents, maturity index of immature to mature, and moderate brittleness. Rocks within the formation tend to be reactive to highly reactive to water, with a moderate degree of swelling capacity. Porosity varies within 5.8 - 7.4 % with permeability ranging from 0.37 to 3.2 mD. Sweet spots in the formation found around Basilam-1 and Securai-1wells occupy about 21% of the formation. On the other hand, Belumai Formation shows moderate to good shale gas potential, with low to high organic material contents, immature to mature levels of maturity, and moderately brittle to brittle. Sweet spot areas in the formation found around the two wells are about 29% of the formation. For Baong Formation, analysis reveals moderate to good shale gas potential, with low to medium contents of organic material, immature to mature in maturity index, moderately brittle to brittle in brittleness, and tendency of being reactive to highly reactive to water but with low degree of swelling capacity. Sweet spots in the formation found around the two wells occupies are roughly 11% of the total formation volume in the area. Basin modeling leading to gas resources estimation for Baong, Belumai and Bampo Formations has led to estimated volumes of 6,379 TCF, 16,994 TCF, and 25,024 TCF, respectively, with a total amount of 48,397 TCF. The resources figures are speculative in nature and do not incorporate any certainty and efficiency factors.
